Answer:

an exothermic process and the change in enthalpy, ΔH, will be a negative number

Water is turned into ice cubes in a freezer is an example of an exothermic process.

An exothermic process can be described as a thermodynamic process or reaction that releases energy from the system to its surroundings, usually in the form of heat, light, or sound.

While an endothermic process is an opposite of an exothermic process where the heat absorbs energy usually in the form of heat. In the physical sciences of chemical reactions, the chemical bond energy is changed into thermal energy (heat).

In exothermic reactions, the heat that is liberated by the reaction occurs the form of the kinetic energy of molecules. The transition of electrons from one energy level to another leads light to being released. This light is equal to the stabilization energy of the energy for chemical reaction.

The freezing of water is an exothermic process as the water becomes solid it releases energy to the surroundings.

Answer:

127.4 newtons

Explanation:

Assuming g = 9.8:

F = ma = 13(9.8) = 127.4 N

The force of a 13 Kilogram ball that has been dropped and has fallen for 1 second, then the force offered by the ball would be 127.53 Newtons.

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

As given in the problem we have to find the force of a 13-kilogram ball that has been dropped and has fallen for 1 second,

The force of the dropped ball = mass of the ball × acceleration due to gravity

The force of the dropped ball = 13 × 9.81

                                                  = 127.53 Newtons

Thus , the force of a 13kg ball that has been dropped and has fallen for 1 second would be 127.53 Newtons.

The size and aperture of the telescopes determine its ability to gather light

and reveal details.

A) Observatory X can detect dimmer stars and Observatory Y reveals more

details.

Reasons:

The benefits of using several small telescopes included the production

high resolution images of bright objects such as binary stars that reveal

more details similar to a telescope with a very large aperture, with a

process known as interferometry, through which a star's diameter can be

determined.

The benefit of a large telescope is its ability to gather light from a source,

thereby making possible to detect a dim light source, such as dimmer

stars.

Therefore;

The single large telescope in observatory X can detect dimmer stars while

the interferometer consisting of five 10-meter telescopes, spread out over a

region 100 meters across can see more detail in its images.

The correct option is; A) Observatory X can detect dimmer stars and

Observatory Y reveals more details.

5. Fill in the blanks with either "More," "Less," or "The Same."

a) If an object has more mass than another object, it will accelerate_less____

b) In order to accelerate an object more, one would need to apply_more____ force.

c) If an equal force is applied to two different objects, the less massive object will accelerate_more___

The answer is less, more and more.

If an object has more mass than another object, it will accelerate less. In order to accelerate an object more, one would need to apply more force. If an equal force is applied to two different objects, the less mass of an object will accelerate more

The acceleration of an object depends directly on the force acting upon the object, and inversely on the mass of the object.

Answer:

5 remainder 5

Explanation:

divide 120 by 2.3

To calculate the time it would take for information to travel a certain distance along a neuron, you can use the formula: Time = Distance / Speed.

Given that the information travels at 120 meters per second and the distance is 2.3 meters:

Time = 2.3 m / 120 m/s

Time ≈ 0.019167 seconds

To convert seconds to milliseconds, multiply by 1000:

Time in milliseconds ≈ 0.019167 s * 1000 ms/s ≈ 19.167 ms

So, it would take approximately 19.167 milliseconds for the information to travel 2.3 meters along a neuron.

In this question we must use conversion factor to calculate the scaled diameters by means of the following direct relationship:

d = k · D     (1)

Where:

The conversion factor is found by using the real and scaled diameter of the Earth:

k = 3.5 cm/12,756 km

k = 7/25512 cm/km

Then, we determine the scaled diameters of the rest of planets:

Mercury                      1.4 cm

An interesting story behind the US penny.  It has been around since 1787 and consisted of primarily a copper, or copper-plated coin.  In 1982 the design was changed, due to the high price of copper.  A zinc core was copper plated to have the same appearance, but less expensive composition.  If one of these pennies is slightly filed to expose the zinc, it can be placed in a strong acid that will react with and dissolve the zinc core.  Fun, but a waste of money.
